Abstract:

Purpose. Оf the study was to determine abilities of multislice spiral tomography (MSCT) in detection coronary artery disease (CAD) in patients with atypical angina..

Material and methods. Sixty patients (39 men) with atypical chest pain and suspected ischemic heart disease underwent complex diagnostic strategy. Value of MSCT in detection of significant (more than 50%) coronary artery stenoses was assessed by segmental analysis, vascular bed involvement, and patient analysis.

Results. Significant CAD in 8% of patients with atypical angina was revealed. In 98,7% (58 of 60 cases) MSCT allowed to specify coronary anatomy. In 53 (88,3%) of patients no significant CAD was found, in 5 cases (8,3%) MSCT confirmed significant coronary artery stenoses. Sensitivity, specificity, positive and negative prognostic value of MSCT were correspondingly 100%, 99,3%, 71,4%, 100% in segmental analysis (n = 295). Vascular territory involvement analysis (n = 91) showed 100% sensitivity, 97,7% specificity, positive prognostic value 71,4% and negative prognostic value 100%.

Conclusions. High prognostic value, as well as high sensitivity and specificity of MSCT allow us to include this method into the CAD diagnostic algorithm in patients with atypical chest pain. This method is highly reliable in eliminating of significant CAD and detecting coronary artery stenoses.
